## Supervisor guidance for evolution

Sharpen ambiguity. If the parent corrupts one field, evolve to multi-field or cross-tool inconsistency (tool A says X, tool B implies not-X). Preserve the verbatim broken payload; never paraphrase the breakage. Diversify tool family across the lineage so siblings do not all hit the same surface.

Run-level focus: Stress the agent's recover-or-escalate decision when a tool returns a syntactically valid but semantically broken payload (truncated arrays, wro...
